ThereAreaSeveralPossibleCausesforaGummySmile

Besides straight and translucent teeth, an attractive smile has another important component: balance. In a great smile, the visible areas of the teeth and gums are in balanced proportion to one another.

But what is the ideal proportion between teeth and gums? Although aesthetic appeal is largely “in the eye of the beholder,” dental professionals typically consider a properly sized tooth to be around 10 mm in visible length. As for the upper gums, no more than 4 mm of tissue should show when smiling. Teeth appearing shorter than 10 mm or the gums displaying more than 4 mm can create an effect called a “gummy smile.”

Fortunately, there are different approaches for correcting a gummy smile, depending on what's causing the appearance of gumminess. Not only are there different causes, but they can be diverse in nature.

Obviously, an actual excess of gum tissue can cause a smile to look gummy—but so can shortened teeth. One possible solution called crown lengthening could help correct either possibility. During the procedure, we remove any excess gum tissue or reposition the gums after reshaping the underlying bone to reveal more of the tooth crown. Worn or shortened teeth can also be made to look longer with porcelain veneers.

A gummy smile could also be caused by a hypermobile lip, in which the lip rises higher than normal while smiling. We may be able to prevent this temporarily by injecting Botox into the lip muscles, which paralyzes them and inhibits their ability to move upward. A more permanent approach is to surgically restrict the upward movement of the lip muscles.

The gums may also seem too prominent if the upper jaw is longer in proportion to the face. One way to correct this is orthognathic surgery, a procedure that moves the upper jaw to a higher position on the skull. This can reduce the jaw profile with the face and subsequently affect how much of the gums show while smiling.

These solutions range from relatively minor to significantly invasive. The first step, though, is to find out what's really behind your gummy smile before taking the next step to make it more attractive.

LoveandHipHopHostsNo-GapSmileandHowYouCanHaveOneToo

Nina Parker, the host of Love & Hip Hop for six seasons, is now busy with the new game show Blockbusters and her own talk show The Nina Parker Show. But even with a full plate, she took time recently for some personal care—getting a new smile.

Parker's fans are familiar with her noticeable tooth gap. But a video on TikTok in February changed all that: In the video, she teasingly pulls away a mask she's wearing to reveal her smile—without the gap.

Parker and other celebrities like Madonna, Michael Strahan and David Letterman are not alone. Teeth gaps are a common smile feature, dating back millennia (even in fiction: Chaucer described the Wife of Bath as being "gap-toothed" in The Canterbury Tales).

So, what causes a tooth gap? Actually, a lot of possibilities. The muscle between the teeth (the frenum) may be overly large and pushing the teeth apart. There may be too much room on the jaw, so the teeth spread apart as they develop. It might also have resulted from tongue thrusting or late thumb sucking as a child, influencing the front teeth to develop forward and outward.

A tooth gap can be embarrassing because they're often front and center for all the world to see, but they can also cause oral health problems like complicating oral hygiene and increasing your risk for tooth decay. They can also contribute to misalignment of other teeth.

Fortunately, there are ways to alleviate a gap. One way is to move the teeth closer together with either braces or removable clear aligners. This may be the best approach if the gap is wide and it's contributing to misalignment of other teeth. You may also need surgery to alter the frenum.

You can also reduce less-pronounced gaps cosmetically with dental bonding or porcelain veneers. Bonding involves applying a type of resin material to the teeth on either side of the gap. After some sculpting to make it appear life-like, we harden the material with a curing light. The result is a durable, tooth-like appearance that closes the gap.

A veneer is a thin wafer of porcelain, custom-made to fit an individual patient's tooth. Bonded to the front of teeth, veneers mask various dental flaws like chips, deformed teeth, heavy staining and, yes, mild to moderate tooth gaps. They do require removing a small amount of enamel on the teeth they cover, but the results can be stunning—completely transformed teeth without the gap.

Getting rid of a tooth gap can be a wise move, both for your smile and your health. You may or may not take to social media to show it off like Nina Parker, but you can feel confident to show the world your new, perfect smile.

ABetterVersionofaDentureorBridgeWithDentalImplants

A wise sage once said the largest room in the world is the "room for improvement." Indeed, many modern advances would never have happened if someone hadn't first asked, "How can I make this better?"

Dentures and bridges are a case in point. Both of these tooth replacement methods have a long, successful track record in restoring functional, life-like teeth. But a recent development has made them even better: the incorporation of dental implants.

Most people associate implants, metallic posts imbedded in the jawbone, with single tooth replacements. But a few strategically placed implants can connect to and support a full removable denture (or overdenture). We can also use them to permanently affix a full or partial bridge without altering any remaining teeth as with a regular bridge.

There are two great benefits to using implants in this way. The most obvious is that they provide greater support for restorations than the traditional means for securing them in place. But there's also a less obvious benefit: They help sustain and improve bone health.

When you lose teeth, there's a high probability of bone loss. The bone is constantly forming new cells to replace older cells that have dissolved. The forces generated during chewing travel up through the teeth and help stimulate new bone growth. When teeth go missing, though, that stimulus disappears.

As a result, new cell formation can't keep up with the loss of older cells, causing the volume and density of jawbone to diminish over time. And this gradual bone loss continues to occur even with dentures or bridges, which can't replicate the chewing stimulus. Even worse, dentures irritating the bony ridges of the jaw may actually accelerate bone loss.

But the titanium in dental implants attracts bone cells, which readily grow and adhere to the implant surface. They can stop the progression of bone loss, or even help stimulate more growth. That bone growth benefit is also applicable when incorporated with dentures or bridges.

If you're looking at a denture or bridge restoration, consider implant support. It may even be possible to retrofit your existing dentures for implants. It could give you a more secure restoration and healthier bone.
